Hi , I am Aravindkrishnan from Coimbatore . I just want to understand the intricacies of knee replacement surgery. My mother in law has to go for Knee Replacement surgery-Revision(Since her primary surgery was unsuccessful ). Our surgeon prefers foreign vendor knee than Indian vendors. Surgeon also says cost difference of foreign suppliers over Indian suppliers is around 2 lakhs (approx. ). Since it is revision , please guide me to choose the type of knee. Do we have quality standard for Indian vendors ?? How good it is ??.
